What is the proper way to wash hands when preparing food?

Using soap and warm water for at least 20 seconds is the proper way to wash hands when preparing food because this process effectively removes dirt, grease, and a significant number of germs and pathogens that could be present on the skin. The combination of warm water helps to dissolve oils that can trap microorganisms, while soap creates lather that further lifts debris and microbes off the skin.

The recommendation for a 20-second duration comes from public health guidelines which emphasize that this amount of time is necessary to ensure thorough cleaning of all areas of the hands, including the backs of the hands, between the fingers, and under the nails. This is crucial in a food preparation setting where cross-contamination can lead to foodborne illnesses. Following this hand-washing procedure is essential to maintaining food safety and hygiene in the kitchen.
